Removes the clksel-based DPLL rate handling from the OMAP3 clock tree.In its place, omap2_get_dpll_rate() now has code to determine whether the DPLLis bypassed. This obsoletes several clocks, which are removed by this patch.

Also, previously, the OMAP2xxx code returned the wrong value for theDPLL rate under some conditions. Move the CORE_CLK rate recalculationto clock24xx.c:omap2xxx_clk_get_core_rate().

Thanks to Peter de Schrijver<peter.de-schrijver@nokia.com> for help debugging and Kevin Hilman<khilman@deeprootsystems.com> for reporting the OMAP2 build problems withan earlier version of this patch.
